SG6741
Description
The highly integrated SG6741 series of PWM controllers provides several features to enhance the performance of flyback converters. To minimize standby power consumption, a proprietary green-mode function provides off-time modulation to.
Key Features
- High-voltage start-up Low operating current (4mA) Linearly decreasing PWM frequency to 22kHz Frequency hopping to reduce EMI emission Peak-current-mode control Cycle-by-cycle current limiting Leading-edge blanking Synchronized slope compensation Gate output maximum voltage clamp (18V) VDD over-voltage protection (auto restart) VDD under-voltage lockout (UVLO) Internal open-loop protection Constant power limit (full AC input range)
